Method Detail

read

public int read()
         throws java.io.IOException

Specified by:

read in class java.io.InputStream

Throws:

java.io.IOException

available

public int available()
              throws java.io.IOException

Description copied from class: RAInputStream

Returns the number of bytes that can be read (or skipped over) from this random access input stream without blocking by the next caller of a method for this input stream. The next caller might be the same thread or another thread.

This abstract class is extended by RAFolderInputStream and RAFileInputStream

The available method returns -1 when no more data because the end of the stream has been reached.

and returns Integer.MAX_VALUE when bytes of data is larger then Integer.MAX_VALUE.
